Designing Cisco Network Service Architectures (ARCH 642-874)
Introduction
The design of the Cisco Service Network Architectures (ARCH), second edition, focuses on how to perform the design, through detailed and a network infrastructure. This design is compatible with intelligent network services solutions for efficient network performance, scalability and network availability. This book allows readers, applying solid Cisco network solution models and best design practices to provide interconnection solutions viable and stable business networks. In addition, the book was written to help candidates prepare for the project examination Cisco Network Service Architectures (642-873 ARCH). This exam is one of the requirements for certification CHRC. This exam tests a candidate's knowledge on the latest developments in design and network technologies, including network infrastructure, intelligent network services and converged network solutions.
